No ka manawa lōʻihi, ua lanakila nā mea hana haole mai ʻAmelika Hui Pū ʻIa a me Iapana i ka mākeke pale ahi o ka honua me ko lākou mau pono i ka ʻenehana, kapikala a me nā ʻano huahana. Ua hoʻomaka ka ʻoihana pale ahi Kina i ka lohi a ke pāʻani nei i ke kuleana o ka hopu. Mai ka makahiki 2006, ua ulu wikiwiki ia.
I ka makahiki 2019, ʻo ka mākeke pale ahi honua ma kahi o 7.2 biliona USD, me ka hoʻomohala paʻa. Ua hōʻike ka ʻāina ʻo Asia Pacific i ka ulu wikiwiki loa. Ke neʻe mālie nei ka manaʻo ʻai i Asia, a ʻo ka piʻi nui mai ka mākeke Kina. I ka makahiki 2019, ua hoʻonui ʻia ka mākeke FR Kina e 7.7% i kēlā me kēia makahiki. Hoʻohana nui ʻia nā FR i ka uea a me ke kaula, nā mea pono hale, nā kaʻa a me nā māla ʻē aʻe. Me ka hoʻomohala ʻana o nā mea polymer a me ka hoʻonui ʻana i nā kahua noi, hoʻohana nui ʻia nā FR i nā ʻano like ʻole e like me nā mea hana hale kemika, nā mea uila uila, ka lawe ʻana, aerospace, nā lako, nā mea hoʻonaninani, nā lole, nā meaʻai, nā hale a me nā halihali. Ua lilo ia i ka lua o ka nui o ka polymer mea hoʻohui hoʻololi ma hope o ka plasticizer.
I nā makahiki i hala iho nei, ua hoʻoponopono mau ʻia a hoʻomaikaʻi ʻia ka hoʻolālā ʻai ʻana o nā FR ma Kina. Ua hōʻike ʻia ke koi o ka ultra-fine alumini hydroxide flame retardants i ka ulu wikiwiki ʻana, a ua emi iki ka mākeke o nā mea hoʻopaʻa ahi halogen organik. Ma mua o 2006, ʻo nā FR home he mau mea hoʻopaʻa ahi halogen, a ʻo ka hoʻopuka ʻana o nā mea hoʻopaʻa ahi phosphorus inorganic (OPFRs) i helu ʻia no kahi hapa liʻiliʻi. I ka makahiki 2006, ʻo Kina ka ultra-fine alumini hydroxide (ATH) pale ahi a me ka magnesium hydroxide flame retardant i emi iho ma mua o 10% o ka huina pau. Ma ka 2019, ua piʻi nui kēia māhele. Ua hoʻololi mālie ke ʻano o ka mākeke pale ahi i loko o ka hale mai nā mea halogen flame retardants i ka inorganic a me nā OPFR, i hoʻohui ʻia e nā mea hoʻopaʻa ahi halogen organik. I kēia manawa, ʻoi aku ka mana o ka brominated flame retardants (BFRs) ma nā kahua noi he nui, akā ke wikiwiki nei nā phosphorus flame retardants (PFR) e pani i nā BFR ma muli o ka noʻonoʻo ʻana i ka mālama ʻana i ke kaiapuni.
Ma waho aʻe o 2017, ua hōʻike ʻia ke koi o ka mākeke no nā mea pale ahi ma Kina i kahi ulu ulu mau a paʻa. I ka makahiki 2019, he 8.24 miliona tons ke koi o ka mākeke no nā ahi ahi, me ka piʻi ʻana o ka makahiki he 7.7%. Me ka hoʻomohala wikiwiki ʻana o nā mākeke noi i lalo (e like me nā mea hana hale a me nā lako hale) a me ka hoʻonui ʻana i ka ʻike pale ahi, e piʻi hou ka noi no nā FR. Ua manaʻo ʻia e 2025, ʻo ka noi no nā mea pale ahi ma Kina he 1.28 miliona tons, a ʻo ka ulu ʻana o ka hui mai 2019 a 2025 e manaʻo ʻia e hiki i 7.62%.
